Ruby on rails 为什么我不能测试我的版本主义路线

我已经像这样对路线进行了版本控制

api_version(:module => "api/v1", :path => "api/v1") do
  match '/files' => 'files#index', :via => :get
end

devise/registrations#edit
                          PUT    /users(.:format)  devise/registrations#update
                          DELETE /users(.:format)  devise/registrations#destroy
             api_v1_files GET    /api/v1/files(.:format)      api/v1/files#index

还有我的控制器app/controllers/api/v1/files_controller.rb

class Api::V1::FilesController < ApplicationController

  def index
  end

end

命令rake routes为我提供了一个如下的路径列表

api_version(:module => "api/v1", :path => "api/v1") do
  match '/files' => 'files#index', :via => :get
end

devise/registrations#edit
                          PUT    /users(.:format)  devise/registrations#update
                          DELETE /users(.:format)  devise/registrations#destroy
             api_v1_files GET    /api/v1/files(.:format)      api/v1/files#index

当我运行rake spec:controllers时，规范会下降

我做错了什么？

通过将RUBY更新到1.9.3解决问题
